Sensors Overview

Note: This section describes the new Tenable.io interface. For information about the classic interface, see Scanners (Classic Interface). For information about navigating the new interface, see Navigate the New Tenable.io Interface.

Tenable.io supports the following sensor types:

  • Tenable-provided regional cloud scanners.
  • Manually configured linked sensors (Nessus scanners, NNM instances, Web Application Scanning sensors, and Nessus Agents)

Cloud Sensors

By default, Tenable provides regional cloud sensors. You can select these sensors when you create and launch scans.

The Tenable.io interface displays regional cloud sensors in the following groups:

  • US Cloud Scanner: A group of scanners from one US-EAST range (Ohio or Virginia) and the US-WEST range.
  • US East Cloud Scanners: A group of scanners from either the Ohio or Virginia US-EAST range.
  • US West Cloud Scanners: A group of scanners from the US-WEST range.
  • AP Singapore Cloud Scanners: A group of scanners from the Singapore AP-SOUTHEAST range.
  • AP Sydney Cloud Scanners: A group of scanners from the Sydney AP-SOUTHEAST range.
  • AP Tokyo Cloud Scanners: A group of scanners from the AP-NORTHEAST-1 range.
  • CA Central Cloud Scanners: A group of scanners from the CA-CENTRAL-1 range.
  • EU Frankfurt Cloud Scanners: A group of scanners from the EU-CENTRAL range.
  • UK London Cloud Scanners: A group of scanners from the EU-WEST range.

The following table identifies each Tenable.io regional cloud sensor and, for whitelisting purposes, its IP address ranges. These IP address ranges are exclusive to Tenable.

Linked Sensors

After you install a Nessus scanner, NNM instance, Web Application Scanning sensor, or Nessus Agent sensor, you can link it to Tenable.io.

Before you can use linked sensors in Tenable.io scans, you must:

  1. Install the appropriate Tenable product on the sensor or the host you want to scan. For more information, see:

  2. Link the sensor or link the agent to Tenable.io.

After linking a sensor, you can:
